This famous drawing satirizes the Champ de Mai 1815, a grand ceremony and parade held in front of the Ecole Militaire during the Hundred Days of Napoleon's return. After a parade of 50,000 soldiers and a 600-gun salute, Napoleon presented the new constitution and representatives of the people swore oaths of loyalty to it. Napoleon appeared in robes of purple velvet and white satin, not in red as shown here. Published after Napoleon's exile to St. Helena, the drawing suggests that on the one-year anniversary of the Champ de Mai, Napoleon will be able to demand oaths of loyalty only from the rats that were known to infest the island.
